This game was previewed at G2E this year but I found it at my local casino this weekend. Whenever you land 3 or more bonus symbols, you have a chance to trigger the progressive feature. If that happens, each bonus symbol will spin around and either be blank or award 1 spin of the progressive wheel. Maybe if you bet more it can award more than 1 spin per symbol, I'm not sure. Also, instead of the choice between the credit prize and free games like in normal China Shores, you choose between Super Free Games, which award a 8x, 12x, or 20x multiplier to every win, or regular Free Games with wins at 2x.
Here's a live play video I took to show off the game - I had a nice line hit and bonus in it.
If this game is at a casino near you please let me know, I'm wondering if we might be one of the first to get it.
